'The Trap' (Story Code 'B505') by Edward J. Lakso

While making their way through the ruins of San Francisco in search of a computer that could play their data disc, Virdon, Burke and Galen are attacked by General Urko and his gorilla troops. But the fight is interrupted when an earthquake suddenly strikes, causing the ground to give way; both Burke and Urko fall into a pit, which is immediately sealed by falling masonry. Finding himself in the remains of what was once the city’s underground system, Burke realises that he must find a way to convince Urko to work with him to find a way out. Meanwhile, on the surface, Virdon and Galen try to form an uneasy alliance with Urko's troops in an attempt to rescue their trapped friend. Urko begrudgingly agrees to spare Burke’s life so that they can escape – but when he sees a poster showing apes caged in a zoo, his anger causes the situation to escalate out of control...
